| Abstract: | The G. 723.1 speech compression coding is realized in the digital base-band walkie-talkie system. Innovation is to fully utilize the processing power of DSP hardware and high-speed CPLD, high integration and programmability for the hardware circuit design, the fixed-point C of G. 723.1 code is optimized for in-depth under the limited of band and DSP resources. Finally, the closed-end can broadcast real-time, continuously and the clear pronunciation that transmit from the start on the self-made hardware circuit. |
